Ivory Coast coach Sven-Goran Eriksson has said that Group G rivals North Korea could be a tough proposition for his side at the World Cup.
The North Koreans - appearing at their first World Cup tournament since 1966 - are very much an unknown quantity, but despite the fact that Eriksson is coming up against Brazil and Portugal in the group, he has his eye on the underdogs.
"Pay attention to North Korea," said Eriksson. "Nobody speaks about North Korea but they play good football.
''Physically they are better than anyone because they have been in the training camp for six months. I think we are going to have three very difficult games, and we have to be very organised."
Eriksson also insisted that Chelsea striker Drogba would be crucial to his side's hopes of progressing in the competition, due to the goal threat he possesses.
"Every team going to the World Cup has one or two players who are match-winners. For us it's Drogba, yes," he added. "He scored over 30 goals this season, and doing that in the Premier League and Champions League. That's absolutely incredible. We want him very fit in the World Cup."
